Positron Emission Tomography

Positron Emission Tomography (PET) is a medical imaging technique that helps doctors see how tissues and organs are functioning. During a PET scan, a small amount of a radioactive substance, called a tracer, is injected into the body. This tracer emits tiny particles called positrons as it breaks down. A special camera detects these positrons and uses the information to create detailed images of the body's metabolic activity. This technique is particularly useful in diagnosing conditions like cancer, as it highlights areas with high levels of metabolic activity, which may indicate disease.
